DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIGS. 1-3, the present invention features a toolbox device 100 for allowing a user to charge a battery pack of a battery-powered tool. In some embodiments, the toolbox device 100 of the present invention comprises an interchangeable charger, which can be used to fit various tools and models.
The toolbox device 100 comprises a first half housing 200 and a second half housing 300. The first half housing 200 has a top 210, a bottom 230, a front, a back, and a side 220. The second half housing 300 has a top 310, a bottom 330, a front, a back, and a side 320. Disposed in the second half housing 300 is an inner compartment for storing tools. The bottom 230 of the first half housing 200 is removably attached to the top 310 of the second half housing 300 via a hinge mechanism, e.g., disposed at the intersection of the back of the first half housing 200 and the back of the second half housing 300. The first half housing 200 can move between multiple positions including an open position and a closed position respectively allowing and preventing access to the inner compartment of the second half housing 300 (for storing tools).
The first half housing 200 and second half housing 300 can be secured in the closed position via a locking mechanism 124 (e.g., disposed at the intersection of the front of the first half housing 200 and the front of the second half housing 300). In some embodiments, a handle 126 is disposed on the device 100, for example on the top 210 of the first half housing 200.
Disposed on the top 310 of the second half housing 300 is a battery pack compartment 110 for receiving a battery pack 130 of a battery-powered tool and an interchangeable charger component 900. The battery pack compartment 110 has an inner surface, wherein charging strips 139 are disposed on the inner surface. The charging strips 139 can operatively connected to the interchangeable charger component 900 when the interchangeable charger component 900 is inserted into the battery pack compartment 110. The battery pack 130 is adapted to engage the interchangeable charger component 900, and the interchangeable charger component 900 charges the battery pack 130 (when inserted into the battery pack compartment 110). In some embodiments, the interchangeable charger component 900 is removable. In some embodiments, the interchangeable charger component 900 is replaceable and interchangeable with other types of charging units so as to suit a user's varying needs (e.g., for charging various types of batteries).
Disposed on the side of the second half of the toolbox device is a male power plug 400. In some embodiments, a power cord 140 (having a female component and a male component) is connected to the male power plug 400. The power cord 140 is for inserting to a standard power outlet (e.g., socket) that is connected to a power supply (e.g., AC commercial power supply). The male power plug 400 can operatively connect via the contact strips 139 (e.g., an via an AC-DC converter unit) to the interchangeable charger component 900 such that when the male power plug 400 receives power via the power cord 140, power is delivered to the interchangeable charger component 900 to charge the battery pack 130.
Disposed on the side 320 of the second half housing 300 of the toolbox device 100 is a toolbox power outlet 450 (e.g., socket) for receiving an alternative power cord of a power tool. The toolbox power outlet 450 is for providing additional power outlets to, a user for such a power tool. The toolbox power outlet 450 is operatively connected to the male power plug 400 (e.g., AC commercial power supply), such that power can be supplied to the toolbox power outlet 450 and thus to the power tools connected to the toolbox power outlet 450. This mechanism is similar to standard devices for providing additional power outlets. In some embodiments, the outlet 450 is equipped with a breaker so as to protect against overload.
In some embodiments, one or more indicator lights 116 are disposed on the top 310 of the second half housing 300. In some embodiments, one or more indicator lights 116 are disposed on the interchangeable charger component 900. In some embodiments, an indicator light 116 signals that the battery pack 130 that is connected to the interchangeable charger component 900 is defective. In some embodiments, an indicator light 116 signals that the battery pack 130 that is connected to the interchangeable charger component 900 is charging. In some embodiments, an indicator light 16 signals that the battery pack 130 that is connected to the interchangeable charger component 900 is fully charged (e.g., ready). The indicator lights 116 may be operatively connected to the interchangeable charger component 900. Charging units with indicator lights that can indicate that the battery pack is defective, charging, or ready are well known to one of ordinary skill in the art. For example, such devices may include a Multi-Volt Battery Charger 7.2-19.2-24V (e.g., Black and Decker).
In some embodiments, an indicator light 116 (e.g., defective indicator light) is illuminated when the battery pack 130 attached to the interchangeable charger component 900 is defective. In some embodiments, an indicator light 116 (e.g., charge indicator light) is illuminated when the battery pack 130 attached to the interchangeable charger component 900 is charging. In some embodiments, an indicator light 116 (e.g., ready indicator light) is illuminated when the battery pack 130 attached to the interchangeable charger component 900 is fully charged.
In some embodiments, a user removes a battery pack 130 from a battery-powered tool and places the battery pack 130 in the interchangeable charger component 900, and further places the battery pack 130 and interchangeable charger component 900 in the battery pack compartment 110 disposed in the toolbox device 100 to charge the battery pack 130. In some embodiments, a user plugs the power cord 140 connected to the toolbox device 100 (e.g., the male power plug 400) into a standard power outlet.
As shown in FIG. 3, in some embodiments, a power supply (e.g., 120 volt AC power input) connects to the male power plug 400, which is operatively connected to an AC-DC converter unit to convert alternating current into direct current. The male power plug 400 (e.g., power input) and/or the AC-DC converter unit is operatively connected to the contact strips 139. In some embodiments, an interchangeable charger component 900 (e.g., “charging unit”) is operatively connected to the AC-DC converter unit (e.g., via contact strips 139) to draw power to charge a battery pack 130. In some embodiments, the interchangeable charger component 900 is operatively connected to one or more indicator lights 116 (e.g., defective, charge, ready). In some embodiments the AC-DC converter unit is operatively connected to the toolbox power outlet 450. In some embodiments, the power supply (e.g., AC power input) is operatively connected to the toolbox power outlet 450.
In some embodiments, the interchangeable charger component 900 is a standard battery charging unit that recharges battery packs. Battery charging units are well known to one of ordinary skill in the art. In some embodiments, the toolbox power outlet 450 (e.g., socket) is a standard power outlet known to one of ordinary skill in the art. In some embodiments, the male power plug 400 is a standard power plug well known to one of ordinary skill in the art. In some embodiments, the locking mechanism 124 is a standard clasp or latch locking mechanism known to one of ordinary skill in the art.
